The mayor of Ukraine's second-largest city was shot in the back, and pro-Russia insurgents seized more government buildings Monday as the U.S. hit Russia with more sanctions for allegedly fomenting the unrest in eastern Ukraine.

Armed insurgents tacitly backed by Moscow are seeking more autonomy in the region — possibly even independence or annexation with Russia. Ukraine's acting government and the West have accused Russia of orchestrating the unrest, which they fear Moscow could use as a pretext for an invasion.

Last month, Russia annexed Crimea weeks after seizing control of the Black Sea peninsula.

In a bid to ratchet up the pressure on Russian President Vladimir Putin, President Barack Obama's government levied new sanctions on seven Russian officials and 17 companies with links to Putin's inner circle. The U.S. is also revoking licenses for high-tech items that could be used by the Russian military. The European Union is also planning more sanctions against Russia, with ambassadors from the bloc's 28 members meeting Monday in Brussels. - AP
